Asus Original Power Adapter

📘 Common Features You’ll See on an Original Asus Adapter

📊 1. Electrical Specifications (Label on the Brick)

• Input:

  Typically 100–240 V AC, 50–60 Hz — this means it works worldwide on standard electricity.

• Output:

  Eg: 19 V DC at 3.42 A (≈65 W) for many standard laptops, or

  20 V DC at 12 A (≈240 W) for gaming laptops.

  The combination of output voltage (V) and current (A) determines wattage (W) — more watts means the charger can deliver more power.

• Connector type & size:

  Barrel plug (e.g., 4.5 × 3.0 mm, 6.0 × 3.7 mm) or USB-C PD port. Always match this to your laptop’s port!

🛡️ 2. Safety & Protection

Original ASUS adapters include built-in protections such as:

• Over-voltage protection (OVP)

• Over-current protection (OCP)

• Over-temperature protection (OTP)

• Short-circuit protection (SCP)

  These keep both the adapter and your laptop safe.

🚫 3. Build Quality

Genuine Asus chargers are:

• Compact and well-made

• Heat-efficient

• Durable cables and strain-relief points

  Imitation or cheap clones may overheat, fail early, or damage your laptop.

🔌 4. Connector Types

Depending on the laptop model:

• Barrel connector — common on many VivoBook, ZenBook, and older models.

• USB-C PD (Power Delivery) — common on newer ultraportables; supports multiple voltages (5V/9V/15V/20V) and can charge laptops quickly.

📏 How to Match With Your Device

To pick the right original adapter:

1. Check the label on your old adapter or your laptop manual.

2. Make sure voltage and amperage match what ASUS specifies.

3. Confirm the connector size/type (barrel or USB-C).

4. If in doubt, use the exact model number of your laptop to find the corresponding adapter.
